How to export tags with OPC-UA

A (very) quick search of the forums failed to answer my question.

What do I have to do to allow my tags (created via module (in-memory I think)) to be exported via the OPC-UA server?

How are you creating these tags? Is your module a driver or no?

It creates DB tags internally and then drives them.

I don’t think it was created as a driver.

Well a tag provider and a driver for the UA server are totally different beasts, so you really only have two options:

  1. Write a driver module.
  2. I think Kyle Chase created a driver that exposes SQLTags as OPC-UA tags, but I’m not sure if it has been maintained or not. You also need to be careful because you can easily get into a reference loop if you then create SQLTags out of those tags…

By driver, do you mean abstractTagDriver? We are using sqlTagManger.

AbstractTagDriver is one option. A driver is anything that implements the Driver interface.

Ok thanks

This might work as well Robert

Thanks Kyle.
